So if I am following correctly, take the example of an array containing `[1,
10, 100]` multiplied by itself, with scale 2 and precision 3
In spark this will result in
```
1: {value: 1, scale: 2, precision: 3},
2: {value: 100, scale: 2, precision: 3},
3: {value: 100, scale: 4, precision: 3},
```
With this PR this will result in a new array with scale 4 and precision 3
containing
```
1: 0,
2: 1,
3: 100
```
I don't follow how this is comparable behaviour?
